Abstract
The flow field in a combustor with leandirect injection (LDI) and discrete jet swirlers is analyzed using a computational-fluid-dynamics (CFD) code with a Reynolds Stress Turbulence Model (RSTM). The results from the RSTM are compared to time-averaged laser-Doppler velocimetry (LDV) data, as well as results from the National Combustion Code (NCC) that has a cubic non-linear k-ε turbulence model. The comparison of result from the two codes indicates that the RSTM does a better job of resolving recirculation zones and high velocity-gradients than the k-ε model. This confirms that the higher-order RSTM is necessary for simulating complex flow fields where separations, strong anisotropy and high swirl are present. © 2001 by the American Institute of Aeronautics and Astronautics, Inc.
